A cycle adjustable water irrigation system and method for crops

Abstract

The embodiment of the present invention discloses a cycle-adjustable water irrigation system for crops, which includes a water-soil interlayer unit for forming stratification in the crop planting soil and forming a direct hydroponic space for the plant root system at the root system of the crops, and also includes The water supply unit, the data acquisition and analysis module, and the water content detection data of the soft soil layer and the water level data analysis results in the water-soil interlayer unit by the data acquisition and analysis module, the atomization and drip irrigation module that controls the work, and the irrigation method is formed first. In the gradient crop planting area, irrigation water channels are set up, and the water supply system maintains the water flow in the irrigation water channels to realize the internal circulation of hydroponics, real-time control of the water level in the irrigation water channels, and combined irrigation by using drip irrigation, so that crops can be planted The water in the soil in the area naturally infiltrates into the irrigation water channel, forming an external circulation of drip irrigation, which efficiently realizes the irrigation of crops and improves the transpiration of plants.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of greenhouse crop planting, and in particular to a cycle-adjustable crop water irrigation system and method. Background technique

[0002] The existing automatic irrigation system for greenhouses generally irrigates evenly, but in fact, the soil moisture distribution in the greenhouse is uneven. The soil near the sides of the scaffold has more moisture infiltration outside the greenhouse and the flow of water droplets on the greenhouse film, so the soil outside the greenhouse The humidity is high, and the middle of the greenhouse is relatively dry.

[0003] And because the transpiration of different crops is different, traditional sensors can only monitor the temperature and humidity changes in the overall crop growth space, and cannot realize different watering controls for different plants. In snowy weather, waterlogging is easy to occur in the greenhouse, and the moisture in th...
